7075 Grade Super Hard Aluminium Sheet Plate 10mm Thick 100mm-350mm Various Sizes

7075 is a zinc-based alloy with significantly higher tensile strength (typically 500–570 MPa) compared to 6061 (typically 270–310 MPa). 6061 is easier to weld and slightly more corrosion-resistant, while 7075 is preferred when maximum strength and hardness are the priority. For structural brackets, jigs, and load-bearing plates, 7075 is the stronger choice.

Yes. 7075-T6 aluminium machines well with carbide-tipped tooling designed for non-ferrous metals. It can be cut with a band saw, milled on a CNC router or manual mill, and drilled with standard HSS or carbide drill bits. Use cutting fluid or lubricant to extend tool life and achieve cleaner finishes.

7075 has moderate corrosion resistance in its mill-finish state. For outdoor or marine environments, anodizing or applying a chromate conversion coating is strongly recommended. Without surface treatment, prolonged exposure to salt air or moisture can cause surface oxidation over time.

Select the size that is equal to or slightly larger than your finished part dimensions to allow for machining allowance (typically 2–5mm per edge). If your part is 95×145mm, the 100×150mm sheet gives you adequate material. Ordering the closest size minimizes waste and cost.

7075 aluminium is generally considered difficult to weld using conventional MIG or TIG processes due to its susceptibility to hot cracking. Mechanical fastening (bolts, rivets) or adhesive bonding is recommended for most applications. If welding is required, consult a specialist familiar with high-strength aluminium alloys.

These sheets are nominally 10mm thick. Standard mill tolerance for aluminium plate at this thickness is typically ±0.3mm. If your application requires tighter tolerances, surface grinding after receipt is recommended. Contact us to confirm if a tighter tolerance certificate is needed for your project.
